:D Beggars can't be choosers :D
To make a long story short...
I have a cousin of mine who likes to buy expensive stuff, gets bored, throws said stuff into a closet and sits on it for years....
Today she calls me to unload a large pair of old school infinity 15'' 3-way pair of speakers. I said to myself, well maybe I could gut them for the woofers and use em to compliment my SB acoustics 2-ways that I put together (sound great, but lack low-end capability at med-high volumes).
As I finished loading up the truck, I asked her if she was still using her Adcom gear( I was gonna make her an offer) and she said "oh you want that stuff too?....it's yours":pepper::pepper::pepper::pepper:
To top it off....she also gave me a SIMA w-3050 class a/ab amplifier :whoo::whoo::whoo::whoo:

Those infinities will sit your ass down... Those and Cerwin vegas were the college frat rockers.
Would not gut them.

I still need to hook these refrigerator sized cabinets and give them a listen, but...
From what I have found on the Internetz, these may end up as workshop duty speakers.
People that have auditioned them, seem to all say the same thing. They are good sounding set of speakers, but lack detail in the mid-range and tend to be a bit boomy. Just the thing I need to piss-off the other tenants :nutkick:
A few have gone through the trouble of bracing the cabinets and applying various forms of dampening to tame the low-end frequency response.
I guess I need to give em a chance and give them some ear time, before deciding.

Re: :D Beggars can't be choosers :D
They can be bright.... I'm not a huge fan of polycell tweets though.
I was looking for a pair when I didn't give a shit about my shop audio.... then I started giving a shit.
Killer for garage. they get fucking loud.. My buddy has a set driven with WAY too much power... You will give up before they do. Especially with that tweet.

Re: :D Beggars can't be choosers :D
I thought those had 4.5" cone midranges.
I have a pair of the clear kappa 2" polydomes, I'm surprised what they'll fetch on the bay sometimes. I see a lot of white ones, by then they're pretty much gone... Pretty loud suckers, they have a 4.2 and 4.3 ohms tested resistance, so 6 ohm versions. They were new pulls from a stereo shop for warranty work and have like, no real use on them. I've tried them in the dash, just to see for a couple of minutes but I was surprised at how much the high end gets harsh, you wouldn't think that pliable poly screeched without a low-pass filter on them. Then again, domes in the dash are kinda funny on placement too.
but I digress.

Re: :D Beggars can't be choosers :D
I found all the poly cell stuff from that era to be rather harsh. Some kid in college had the 8"clear woofer/poly cell tweet. Goddamn they would drill a hole in your eyeball.
-
Re: :D Beggars can't be choosers :D
what's cool about the kappa poly dome that came in the RS series, is they are extremely flat. They use a wafer of samarium-cobalt magnet, the whole magnet assembly is about 3/4" thick with the dome standing up a 1/2" from the face plate. There's a plastic enclosure filled with jute that is just glued to the back, that when removed reveals the whole dome assembly is about 1.2" thin.
I never got to audition the polycell stuff that much, never bought any myself, but it seemed to me Infinity was always trying to get high efficiency out of their home speakers, I guess that's partly why people want the replacement parts and pay high from the resale market. They were built using components that for the time, were hard to equal with an equivalent. I don't know if anyone was successful in putting together a 5" polygraph dome like they did, that was a specialty piece, along with the EMIM/EMIT stuff.
I wonder if the Infinity 15" polycell series was louder than say, the C-V 15" D series, at that time..

Re: :D Beggars can't be choosers :D
I edited out the word DOME out of the midrange description. They are definitely cones.
Good catch Caj.

used to gawk at the SM series in Crutchfield, back in the day.
I believe those polycell foam membrane tweeters had reliability problems, you don't see that material used for tweeters anymore.
I wonder if you made a polycell-type dome out of carbon nanotubes, if it would be special..

Re: :D Beggars can't be choosers :D
My back is feeling better... I think I will wrestle those infinitys out of my garage and have emailed play some tunes :D

No, Vega had the corner. They used a real compression-ish tweeter, a decent mid and a wonderful cast frame woofer that had a hell of a motor. They were built as more of a prosumer thing with a woodgrain cab. The D9, similar driver compliment.. the AT series went to a more stout horn loaded dome, you could tell it was under stress what high levels.. Still killer but somehow the D series got loud as hell and still remained somewhat listenable even at high levels.
Years ago I found a set of D3's I refurbed for my kid for a total cost of 50 bucks. Even after I've all growed up I still find them pretty decent tonally to listen to. and for a 10" they make ungodly low end for music. Wife is still pissed at us over that.
This is in no way intended to indicate that the infinity SM series were slouches.

that sounds right, I didn't own that much C-V stuff, but they used to use their rating system to good effect, with the "max SPL 125 db" thing, I saw other more pro-sumer offerings use. I find it extraordinary how long CV was able to maintain production in their facility, I think they were one of the last hold-outs on American made goods.
I still have an LE-12D basket and perfect coil, I'd like to get put back together because I enjoyed their sound back in the day.
I guess Klipsch is one of the greats too, I have fond memories of a local night club where the dance floor consisted of 4 La Scala flying above the floor, aimed into the crowd.... a square about 30 by 40 or so, nice and loud.
used to want to have that same sound when I got the money together, funny how things progress as we get older.

Holy crap, these things are efficient!
I hot swapped from my 89db SB cabs to the 102db Infinitys and scared myself for a sec. (listening to Pantera's Vulgar Disp...)
Well my initial thought is, not too shabby...ugh, wtf.......

Was fun while it lasted.:thumbdown::thumbdown::thumbdown:
Not even long enough to swap CDs.

Re: :D Beggars can't be choosers :D
you can fix that rather easily.
Comes with the territory.
It's how I score cheapass vegas!

Re: :D Beggars can't be choosers :D
I will look into that, thanx.
Uhh, any pointers?
Appreciate it ;)

Re: :D Beggars can't be choosers :D
Parts express has a universal re-foam kit that someone used to re-do his SM-150s.

I purchased a speaker foam repair kit to fix the surrounds on a pair of Infinity SM-150's, after reading the reviews, and someone had repaired the same series, so I knew there was a track record of the kit fitting these particular speakers, and after watching the tutorial on how to do the installation of the surrounds. Took less than an hour, actually took much longer to remove the old, than it took to install the new. The speakers look new again, and sound like they should.
Would you recommend this product to a friend? Yes
EDIT>>I found the brand correct kit for the same price http://www.speakerrepair.com/page/pr...016-B-INF.html

Re: :D Beggars can't be choosers :D
a surround replacement tutorial?
that would be a wee bit exciting..
like a build thread, if you post it, they will come.
-
Re: :D Beggars can't be choosers :D
there may be one on MSS.
I'll look up the surrounds, the universal ones are not so universal.

Re: :D Beggars can't be choosers :D
After doing a bit of research on re-foaming surround, I took out one of the woofers to further evaluate the operation.
I was surprised to see that the whole woofer weighs like 4-5 pounds. My xls/hds8 have bigger motors!!!:heh::heh::heh:
Well I am going to pull the trigger on a re-foam kit and fix these suckers up and re-enforce/dampen the cabinets, because they resonate like a Jamaican steel drum.
A coat of bedliner to give them a garage duty look and I will have some kick-ass shop speakers.

Re: :D Beggars can't be choosers :D
If you need surrounds give http://newfoam.com/ a call. That's where i got the foam for my AR9LSi's. They have a diagram to show you how to get the measurements they need.
